The break statement is legal only in loops or switch statements. In a loop, it is used to terminate the loop prematurely when the flow of the program eliminates the need to continue the loop. In the switch statement, it is used to prevent execution of cases following the selected case and to exit from the switch block.
A label may be used to indicate the beginning of a specific loop when the break statement appears within a nested loop to terminate execution of a loop other than the innermost loop. A label consists of a legal identifier, followed by a colon, placed at the left margin of the work area.
For an example, see switch Statement.
